LIQUID-METAL-TRANSFER APPARATUS.

Specification of Letters Patent.

Patented Aug. 2, 1921.

Application filed January 30, 1917. Serial No. 145,439.

To all whom it may concern:

Be it known that I, EDGAR J. REILLY, a. citizen of the United States, residing at oungstown, Mahoning county, Ohio, have invented a new and useful Improvement in Liquiddiletal-Transfer Apparatus, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of th s specification, in which Figure 1 is a side elevation partly diagrammatic of apparatus embodying my in vention;

Fig. 2 is a front view of the same;

Fig. 3 is a view similar to Fig. 1, but showing a modification;

Fig. d is a detail view illustrating another method of operation.

My invention has relation to apparatus for the transfer of liquid metal, and more particularly to means whereby the liquid metal delivered by a furnace may be trans ferred to molds or the like.

The object of my invention is to provide apparatus of this class which is simple and convenient in its construction and arrangement, and which will also provide what is known as a low pour. That is to say, apparatus in which the transfer vessel is so constructed and arranged that there will be very little drop from the delivery edge or spout thereof to the mold or receptacle into which the metal is poured, thereby minimizing splashing of the metal.

A further object of my invention is to provide apparatus of this character which may be used as a mixer for the purpose of equalizing the metal received from the furnace. till another object of my invention is to provide apparatus of this character by means of which liquid metal may be simultaneously received from the furnace and delivered to the molds.

My invention will be best understood by reference to the accompanying drawing, which will now be described, it being premised, however, that various changes can be made in the details of construction and arrangement of the parts, without departing from the spirit and scope of my invention as defined in the appended claim.

In this drawing, the numeral 2 designates a delivery spout which is connected with a furnace (not shown) in which the metal is melted. 3 designates a ladle-like receptacle provided with pouring spouts 3*, which is designed to receive the metal from the spout 2 and transfer it to the mold receptacles, or to a runner leading thereto, a portion of which is indicated at 4.

The vessel 3 is provided on eachof itstwo opposite sides with the two bearingmembers 5, which rest in open bearings 6 on a fixed stand or support 7. These members 5 ma be earned by plates 8, securedto the ladle and also provided with projections 9 for engagement with a crane hook or other liftlng means. The ladle is also providedjat each of its opposite sides with two bearing.

at-a higher level than In the operation of pouring the ladle, it is first tilted upon the members 5 until it comes to a position in which the members 10 will engage and rest in the bearings 13. Any further tilting movement of the ladle will then lift the members 5 out of engagement with their bearings, the movement thereafter being wholly upon the members 10 until the final position indicated in dotted lines in Fig. 1 is reached.

By mounting the vessel 3 upon a fixed stand, the vessel can be made of large capacity, sufiicient, if desired, to take the entire cast of a blast furnace. By using a large vessel of this character, it serves the purpose of a mixer to equalize the metal coming from the furnace, and thus make the product of substantially uniform analysis. The stand being fixed, can be located near the furnace, thus making the use of locomotives and ladle cars unnecessary, and greatly reducing the cost of installation'as well as the cost of operation, upkeep, etc.

In Fig. 3, I have shown a modification of the apparatus in which the stand or support 12 is extended to a greater height relative to the bearings 6 so that the upper bearing member 10 of the ladle will. normally rest which may be carried in said bearing 13. The runner P is also raised to a corresp0nding extent. In this form of the invention, there is no initial tilting movement on either one of the bearing members 5, but the tilting movement starts on the bearing 13". This gives a still shorter pour.

By arranging the spout 2 as shown in Fig. 4, and slightly tilting the vessel 3", as also shown in said figure, the liquid metal may be received from the furnace and poured into the runner 4 at'the same time. The metal will ordinarily flow into the vessel more rapidly than it is poured out, but the operator, by raising and lowering on the tilting device let", can maintain a uniform pour, notwithstanding variations in the quantity of the metal being delivered from the furnace. In this manner, the delay of some twenty to thirty minutes ordinarily required 7 to pour a cast into the vessel 3 may beobviated.

The advantages of my invention will be readily apparent, since it provides a simple form of apparatus, whereby liquid metal delivered by the furnace may be transferred to the molds by means of a tilting vessel, in which there will be, in all of the pouring positions of the vessel, but a slight drop between its pouring lip and the mold.

I claim:

The herein described apparatus for transferring molten metal from a melting furnace to molds, comprising a trough extending from a metal furnace, another trough for carrying the metal to the molds, and having its receiving end separated from and at a lower level than the discharge end of the first-named trough, a stand placed intermediate the adjacent ends of the two troughs, said stand having one set of open bearings at a lower fixed level for supporting a ladle'in upright position and another set of open bearings at another fixed level to be engaged by the ladle when tipped, and a large capacity open top, top-pour, metalreceiving and mixing vessel tiltably mounted on said stand in a position to receive metal from the first named trough and to discharge it into the second named trough, said troughs being generally fixed with respect to said vessel and the latter being tiltable between said troughs, substantially as described.

In testimony whereof, I have hereunto set my hand.
